that I, FRANK L. Burr, a

Beit known United States, residing at citizen of the Wichita, inthe-'county'of Sedgwick and.

State of Kansas, have invented a new and "useful Traffic Signal,ofIwhichthe following is a specification. 1

ThlS lnvention relates to trafiic signals for use on vehicles andprimarily designed for attachment to motor vehicleswhereby' thedirection in which the vehicle is about to move can be plainly indicatedto the occupant of a following vehicle or to a person in the path ofsaid vehicle.

Another object is to provide asimple and can be attached readices of askilled mechanic. I

A still further object is to provide a device which is easyandconvenient to operate and which can be actuated so as to indicate aright or left turn, a stop, or a reverse or backlng movement.

With the foregoing and other objects inview which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts which will be hereinafter morefully described and pointed out in the claim, it being understood thatvarious changes may be made in the construction and arrangement of theparts without departing from the 'spirit or sacrificing any of theadvantages of the invention as set forth in the appended claim.

In the accompanying drawings the preferred form of the invention hasbeen shown.

the plate 1, as shown at 6. The two jaws 2 and 5 are adapted to receivebetween them a' supportingstructure 7 which, in the present instance, is-one side of the frame of a windgrip the support 7.

A bearing pin shield, By tightening the nut- 8 on the bolt V A 4 the aws5 and 2 will'be-caused to tightly Journaled on this pinbetween the plate1 v and the washer 10 is a gear 11 whichmeshes with another gear 112journaled on a pin 13-. This .pin extends from the plate 1 and isengaged by a spring washer 14 on the pin.- An arm 15 l is secured to thegear 12 by means of one or more rivets 16- and is preferably shaped tosimulate the arm of a per son, there being the representation of a handat the free end thereof, as shown at 17. A'spring strip 18' is securedto the plate 1 preferably by the pin 13 and bears'against a ball 19loosely mounted in an opening 20 in the plate 1. This ball is adapted tobe seated 1n any one of a series of notches 21 formed in'the gear 12 sothat when the said gear is rotated to bring the arm 15 to any one of aseries of positions, the ball will become seated in one of thenotches'and hold the arm in such position.

A housing plate 22 is mounted on one face of the plate 1 and has anopening 23 into which the plate 3 extends, as shown in Fig. 3. Thisplate 22 extends over, under and to one side of the plate 1 andthe gearsthereon and close to the arm 15.

housing plate is located at the other side.

of the arm 15, as shown at 24 and extends- Another Extendingrearwardlyfrom the inner side of the plate 1 is a bracket. 27 on which isjournaled a segmental gear 28 having a hand lever 29 extendingtherefrom. Gear 28 meshes with the gear 11 and is provided on itsexposed face with designating charactrue, as shown in Fig. 2. Forexample the gear may be provided with the letter N, designating theneutral or downwardly hanging position of the arm15. A letter Rfcan beprovided for indicating when the arm is in a downwardly inclinedposition to signal a turn to the right.v A letter FS may be provided forindicating when the arm is in a horizontal position to signal a stop. Aletter L may be provid'ed for indicatingan upwardly incliifi position ofthe arm 15 to signal a left turn, and the letter B may be provided forindicating an upstanding vertical position toslgnal a backwardorreverse; movement of the vehicle. An index or pointer 30 is arrangedon the bracket and by pulling the,

lever 29 so that theselected letter wi'llreg; ister' with this index thearm 15 willbe; brought to the position desired. The vari-- ous positionsof the arm 15 have been illusstoodthat the arm will be held in anyone ofits positions by the seating of the. spring;
